The NASA/ESA Hubble Space Telescope has revealed a never-before-seen optical alignment in space: a pair of glowing rings, one nestled inside the other like a bull's-eye pattern. The double-ring pattern is caused by the bending of light from two distant galaxies that both lie behind a foreground massive galaxy.
A giant cloud of hydrogen gas is speeding toward a collision with our Milky Way Galaxy, and when it hits -- in less than 40 million years -- it may set off a spectacular burst of stellar fireworks.
A new theory on "First Passage Time" may have profound implications for life sciences, ecology and more
Why does it take so long for soul mates to find each other? How does disease spread through a person's body? When will the next computer virus attack your hard-drive?
A new theory published last month in Nature on the statistical concept of "First Passage Time," or FPT, may provide the key to answering at least a few of these questions, says theory co-author Prof. Joseph Klafter from The Raymond and Beverly Sackler Faculty of Exact Sciences's School of Chemistry. And the answers may lead to breakthroughs in medicine, mathematics, the environment, and elsewhere.

Challenging the long-held notion that it was the Europeans who were the first non-native visitors to the Americas, a Mongolian professor of history has claimed that the Mongols reached the American continent first.
"About 8,000 to 25,000 years ago, Mongols with stone tools crossed the Aleutian Islands and arrived in America first," Sumiya Jambaldorj, a history professor from Chingis Khaan University, said Thursday.
Jambaldorj's claim is based on his study of place names in America and their similarity to names in the Mongolian language.

Just when you think you've heard all the possible far-out theories behind the High Frequency Active Auroral Research Program (HAARP) in Alaska, leave it to the Russians to come up with one better. Forget mind control, the Russians think HAARP is a "geophysical weapon" that's gonna capsize the planet. HAARP, just by way of a reminder for those who don't obssessively follow its progress, is a military project that's supposed to study the ionosphere and "use it to enhance communications and surveillance systems for both civilian and defense purposes." In more recent years, the Pentagon has also expressed interest in using HAARP to mitigate the effects of high-altitude nuclear explosions. However, HAARP's use of an antenna array operating in the High Frequency (HF) range has also prompted tons and tons of other theories about its uses, ranging from weather control to altering human behavior.
Call it the rule of unintended consequences - drop your guard because one threat goes away and an unexpected menace jumps up and smacks you. And new research shows it even applies to African acacia trees.
For thousands of years these thorny shrubs have provided food and shelter to aggressive biting ants, which protect the trees by attacking animals that try and eat the acacia leaves.

| This undated handout photo provided by the journal Science shows scale-tending by an ant species. One of the ways in which the mutualism breaks down is that ants become more antagonistic towards plants by increasing their tending of these parasitic scale insects. |
A team of scientists from the Naval Research Laboratory (NRL), the Air Force Research Laboratory's (AFRL's) Research Vehicles Directorate, Kirtland Air Force Base, N.M., and the University of New Mexico (UNM) has detected the lowest frequency radar echo from the moon ever seen with earth-based receivers.

Scientists at University College London have discovered how two proteins called BERT and ERNI interact in embryos to control when different organ systems in the body start to form, deepening our understanding of the development of the brain and nervous system and expanding our knowledge of stem cell behavior.
Four years of observations from the European Space Agency's Integral (INTErnational Gamma-Ray Astrophysics Laboratory) satellite may have cleared up one of the most vexing mysteries in our Milky Way: the origin of a giant cloud of antimatter surrounding the galactic center.
Two old stars may be undergoing a second episode of planet formation, long after their initial window of opportunity.
